Abstract: Abstract Turbine Vane Nozzle Reclassification A gas turbine vane (1) is subject to distortion and wear during operation or repair which results in an increase in the spacing between successive vanes (6 and 7) which define nozzle gas flow areas (8 and 9). During refurbishment, the nozzle spacing must he returned to the original dimension to insure optimum turbine performance.  A build up of alloy in the wear area is accomplished by controllably applying layers of a tape (12) of uniform thickness to the vane.  The tape includes a mixture of a binder and an alloy powder, which is compatible with the substrate alloy, with the mixture formed into a sheet of uniform thickness and having an adhesive backinq.  After applying the tape in layers to a desired thickness, the vane is heated to a temperature at which the binder and adhesive decompose and the alloy in the tape diffusion bonds with the substrate alloy. Utilization of this process reduces the cost of refurbishing, used turbine vanes and avoids hot forminq or bending processes which could damaqe the vanes.

Abstract: ABSTRACT OF THE DISCLOSURE          A process for the manufacture of a heat exchanger from a thermoplastic polymer especially a polyamide, is disclosed.  The heat exchanger comprises two generally planar panels formed from a composition of the polymer, bonded together to form a labryinth of fluid passages between the panels that extend between inlet and outlet means.  The labyrinth occupies a substantial proportion of the area of the panels.  The process comprises coating a first panel with a first coating in a pattern corresponding to the fluid passages of the labyrinth, and coating the second panel with a second coating composition in at least those areas where a bond is to be formed with the first panel.  The coating compositions are selected so that under the influence of heat, the second coating composition will bond to the polymer composition but not to the first coating, thus the first coating acts as a resist coating.  The coated panels are brought into contact and heated so as to effect bonding, and then the passages are expanded e.g. by applying a pressure of a gas to the fluid passages between the panels.  The expanded fluid passages should be heat set so as to reduce distortion during use of the resultant heat exchanger.  Depending on the polyamide selected for fabrication of the heat exchanger, the heat exchangers may be used in a variety of end uses, including in automobiles.

Abstract: Abstract A mounting device and head support structure for carrying optical equipment, such as night vision goggles, on the head of a person, and including a structure which permits ready mounting and dismounting of the mounting device and the optical equipment carried thereby and also easy adjustment of the optical equipment in a vertical direction as well as along the line of vision after mounting. The mounting device includes a lever mounted in a housing and engagable by the user's hand when the mounting device and the optical equipment are grasped for mounting, and the lever is movable to a position to unlock engaging parts so as to permit the mounting device to move relative to the head support assembly and/or permit the part of the mounting device to which the optical equipment is attached to move relative to the housing. The two directions of movement are at 90° relative to each other, i.e., one is in the vertical direction and the other is in the horizontal direction, so as to be able to adjust the height of the optical equipment relative to the line of vision and to adjust along the line of vision. Additionally, it is possible to provide between the part of the mounting device which carries the optical equipment and the housing a pivot axis and adjustment member for engagement as well by the mounting hand of the wearer to accomplish a desired tilt of the optical equipment relative to the normal line of vision. The parts which provide the sliding connection between the housing of the mounting device and the head support assembly may be formed to permit complete separation when the lever is moved to an unlocking position so that the single lever can be activated to accomplish both mounting, dismounting and adjustment in the two directions indicated above. The head support assembly is designed to be worn continuously whenever it may be desirable to mount the optical equipment and permanently carries one of the separable parts in position exposed in front of the wearer's forehead. The head support assembly includes a main head piece which has a relatively rigid portion in the front and more flexible side and top pieces for fitting to a variety of head shapes. Webbing members connect the head piece to a chin piece and are of adjustable nature to provide strong securement to the wearer's head while permitting adjustment.

Abstract: Abstract of the Disclosure A magneto ignition system includes a rotating magnet driven past a primary winding for firing the engine.  The magneto generates a speed dependent signal having a following current pulse and a leading current pulse of a smaller amplitude than the following pulse.  A Darlington power transistor has a collector connected in series with a voltage dropping resistor or diode to the winding.  A resistor bias circuit connects the primary winding to the input of the power transistor.  A cut-off transistor is connected to by-pass the bias circuit of the Darlington power transistor and thereby generate a pulse in the primary winding.  A timing capacitor is connected to the primary winding in series with a diode and charging resistor.  A control transistor has its input circuit connected between the timing capacitor and the resistors of the bias circuit.  The control transistor responds to the differential of the bias circuit voltage and the capacitor voltage, whereby the control transistor drives the cut-off transistor to turn off the power transistor during the decreasing side of the winding circuit after it peaks at starting and low speeds and progressively increases with a gradual advance during the starting speed range, and includes a maximum advance established prior to the peak current value. In another embodiment, a full wave bridge rectifier connects the primary winding to the Darlington power transistor with one diode element connected in series with the collector as the voltage dropping element.  A resistor and diode connect the primary winding to the control and cut-off transistors and the input bias circuit of the Darlington power transistor.
